Supervisor: Filippo Mannucci
I am a postdoctoral researcher in the Extragalactic group at INAF OAA, which I joined in December. I obtained my PhD in November 2024 from SISSA in Trieste. My doctoral research focused on the observational study of Active Galactic Nuclei (AGN) feedback on their host galaxies. In particular, I combined multi-wavelength data of nearby active galaxies.
At INAF OAA, I am expanding my expertise by investigating the properties of the dual AGN populations. Dual AGN are systems hosting two AGN, each powered by accretion onto distinct supermassive black holes (SMBHs). These systems represent the natural precursors of coalescing binary SMBHs, which are strong emitters of low-frequency gravitational waves.

I am a stellar spectroscopist working on the determination of stellar properties and element abundances of FGK type stars. My work consists of developing and calibrating methods in order to quantify the accuracy of state-of-the-art models, and nullify data processing biases. I am lately acting in two fields. The first one consists of providing accurate and precise element abundances of metal-poor red giant stars. The second one is known as Galactic archaeology, where I research the first stages of the Milky Way formation and evolution.

I am a Mechanical Engineer, who graduated in Mechanical Design and Modeling at the University of Bologna.
My master's thesis was focused on the study of innovative Acoustic Meta-Material (AMMs) for soundproofing solutions with ventilated cross sections. At UNIBO, I developed a numerical model for the multiphysical design of AMMs, combining both CFD and Acoustic physics, for the development of AMMs' frequencies tuning design.
A strong and constructive curiosity, led me to range across different types of engineering problems, starting from automotive (during my University path), passing through acoustics (playing a little guitar), to arrive here at INAF Arcetri as a research associate for the opto-mechanical design and simulation analysis of the high-resolution spectrograph for the Wide-field Spectroscopic Telescope (WST).
I can't wait to get to know this world in depth and to be able to contribute to the achievement of useful results.

I am a postdoctoral researcher here at INAF Arcetri as a part of the group StarDance - the non canonical evolution of stars in clusters. I did my PhD at the University of Bologna working mainly on the chemical characterization of some peculiar globular clusters such as Omega Centauri and Liller 1. My work was focused on the analysis of light elements and the anticorrelations present within clusters in order to understand how these systems formed and evolved.
Now, within the StarDance group I hope to bring my expertise in the spectroscopic analysis to help to understand how multiple stellar populations formed in globular clusters.
Sara Saracino
Supervisor: Elena Pancino
I’m an observational astrophysicist, working on resolved stellar populations and I recently joined the Observatory of Arcetri as a postdoctoral researcher within the ERC-funded “StarDance” group. I earned my PhD in Astrophysics and Cosmology from the University of Bologna, followed by a postdoctoral position at the Liverpool John Moores University, in the United Kingdom, where I’m currently an Honorary Fellow. My main expertise is on massive star clusters, both in the Milky Way and satellite galaxies, studied through high spatial resolution photometry (also assisted by multi-conjugate adaptive optics) and multi-epoch integral field spectroscopy. In the StarDance group I will target binary systems in crowded fields and exploit both proprietary and archival data to characterize their orbital properties (mass ratio, period etc.) and identify peculiarities in their chemical abundances.
Ilaria Ruffa
Supervisor: Federico Lelli
I am an observational astronomer working in the field of galaxy formation and evolution. My studies mainly consist in detailed multi-scale investigations (both in line and continuum) of nearby galaxies and AGN,
aimed at characterising the nature of the observed properties of the system, as well as at searching for signatures of super-massive black hole fuelling and feedback and their connection with the host galaxy evolution. I have experience in dealing with multi-wavelength data from the radio to the X-ray regime using a variety of instruments (e.g. JVLA, MeerKAT, ATCA, VST, Chandra, XMM), but I am particularly specialised in the reduction and
analysis of data from the Atacama Large millimetre/sub-millimetre Array
(ALMA).
